An anonymous reader writes with news that the Maryland Attorney General is arguing that anyone who has ever used a smartphone knows it's tracking them, so no warrant is needed for stingrays. Techdirt says: "Up in Baltimore, where law enforcement Stingray device use hit critical mass faster and more furiously than anywhere else in the country (to date...) with the exposure of 4,300 deployments
in seven years, the government is still arguing there's no reason to bring search warrants into this. The state's Attorney General apparently would like the Baltimore PD's use of pen register orders to remain standard operating procedure. According to a brief
filed in a criminal case relying on the warrantless deployment of an IMSI catcher (in this case a Hailstorm), the state believes there's no reason for police to seek a warrant because everyone "knows" cell phones generate data when they're turned on or in use
The brief reads in part: 'The whereabouts of a cellular telephone are not "withdrawn from public view" until it is turned off, or its SIM card removed. Anyone who has ever used a smartphone is aware that the phone broadcasts its position on the map, leading to, for example, search results and advertising tailored for the user's location, or to a "ride-sharing" car appearing at one's address. And certainly anyone who has ever used any sort of cellular telephone knows that it must be in contact with an outside cell tower to function.'"
